Sir I have a doubt Even in variable size partitioning, once the memory is full, we will have to use the block where another process is stored. So, if the new process is smaller than the most appropriate block we could choose, won't it still cause internal fragmentation?

I have a doubt regarding fragmentation in variable size partitioning. How fragmentation occurs in it? there are only 2 cases... case 1: Internal frag. (not possible) case 2: External frag. (how is it possible?) because if we allocate variable sized partitions continuously, then if say we are left with 3kb free space and suppose new process has a size of 4kb. Then there is no space actually left for allocation. So it is the case of insufficient space instead of external frag. So, can u brief about how external frag takes place in variable size partitioning?

sir in variable size partition it seems that it not only free from internal fragmentation but it can also remove external fragmentation. because when partition been created as per the size of process in run time, then where is the scope of external fragmentation??? because each process can be allocated as per its size in different partition.. and in external fragmentation says ,"memory available but cant allocate", but here if memory avaliable it must allocate. am i right????? please look into this sir...........

8:51 We have 3KB as an available memory space but suppose two processes of 1KB each come then effectively we will have 2KB and left with 1KB out of 3KB so this seems to be INTERNAL FRAGMENTATION in variable size partitioning too.
@hrithiksarma29344 жыл бұрын
@Rohit, Interal fragemtation occurs when inside a partition a process is placed and some memory is left . that happens when you partition the memory first called as fixed partitioning.But if a process is placed directly in the available memory space available and the next process is placed in the next memory space it is called variable partition as partition is not done before. therefore the memory space that is left after we have allocated space to all other processes that is actually external partitioning. if it was the case that you had 2 partition of 3 kb each , and 2 process of 1 kb (example of fixed partition )then 1 partition would have 1 process leaving 2kb space useless already , and then process 2 in next partition leaving 2 kb useless after that is internal fragmentation , if it was variable partitioning then in total of 6 kb directly 1st and then 2nd process would have taken the first 2 kb slots in memory leaving the rest 4kb aside ..that is actually external fragmentation.. therefore what you have mentioned is actually external fragmentation.
